It made a strategic choice to grow its membership by organizing the increasingly dominant transnational corporations in Turkey's transportation and logistics sector. n Using its associational power resources of membership participation and internal cohesion, and actively developing the support of the International Transportation Workers’ Federation and UNI Global Union, TÜMTIS ran successful organizing cam­paigns at UPS and DHL. n Trade Unions in Transformation is an FES project that identifies unions’ power re ­sources and capabilities that contribute to successful trade union action. This study features among two dozen case studies from around the world demonstrating how unions have transformed to get stronger.
